Aluminum maker struggles to restart operations after cyber attack

Norway-based aluminum producer Norsk Hydro A.S.A. has yet to restore normal operations after a ransomware cyber attack hit the company's IT systems on March 18, Reuters reported. The attack forced Norsk Hydro to shut several plants and operate its smelters in Norway on a manual basis. Norsk Hydro said that it did not plan to pay the hackers to restore files and would instead seek to restore its systems from backup servers.
